Optimising harvest operations against weather risk2% results in yield and quality losses. Losses due to rain on the mature crop cost the grain industry around &A 30 million annually (&A 1 = &US 0.75). These los ses are significantly higher in the northern wheat belt of Australia due to a dominant summer rainfall which coincides with the harvest per

The impacts of c1imate change on rice yield: evaluation of the efficacy of different modeling approa Mechanisms of plant response to these changes need to be incorporated in models that predict crop yield to obtain an understanding of the potential consequences of such changes. The objectives of this paper are (i) to review climate change predictions and their reliability, (ii) to review the major

A systems approach to the assessment and improvement of water use efficiency in the North China plaifrom many current ones in that, firstly, only the water entering the system as precipitation and inflow is considered water income, and only the water leaving the system through evapotranspiration and into the sea is considered lost; secondly, the dependence of yield on water supply is analyzed on t

Soil data for crop-soil modelss five levels were defined, ranging from farmer’s knowledge and expert systems to use of complex simulation models. Any problem to be studied should be analyzed thoroughly beforehand and the most appropriate level of study should be established for each discipline. Field monitoring of soil physical

Adjustment of nitrogen inputs in response to a seasonal forecast in a region of high climatic risksemi-arid climates. Traditional agricultural experimentation has examined fixed strategies of fertilizer management, but farmers frequently make tactical adjustments to their management in the light of what they perceive as information relevant to the prospects for the forthcoming crop. In this pape

Root ventilation, rhizosphere modification, and nutrient uptake by ricesulting from the soil reactions and their consequences for reactant mobility. Some model predictions are given and their implications for nutrient uptake and the design of nutrient-efficient germplasm and improved nutrient management are discussed.
